What Are The Advantages Of Segment Displays?

Although Segment displays are an older technology, it is still one of the most popular. After all, they cannot display all the colors of a TFT or OLED like what can be seen on a cell phone and tablet.

Why?Below are key reasons why people keep designing these LCD displays into new products.


Lowest Piece Price


The unit price of a segment display can range from less than $0.50/piece to $15/piece depending on quantity, size of glass, and other variables.


Lowest Tooling Fee

The tooling fee for a custom display is the lowest of all the technologies and allows the customer to receive a LCD that is manufactured to the exact dimensions requested, including custom icons and segments.


Focus LCDs offers a one-time NRE (Non-recurring engineering) or tooling fee. This includes all design, technical support, and samples. A PDF showing an overview of our tooling process can be found by clicking here: Custom LCD Flowchart


Low Power Consumption
Segment displays require less power than other display technology such as TFT, OLED, and UWVD. This makes these LCDs ideal for applications that are battery powered or solar powered. They require the lowest power to drive, an estimated 2uA per centimeter squared. Glass only displays (no backlight and no controller) require an estimated 10% of the power that is required for a LED backlight. In other words, a static display without a backlight will draw around 1mA; the same display with a LED backlight will demand from 10mA up to 25mA. Most displays can be driven at 3.3V or 5V since microprocessors can operate at both voltages. 3.3V is becoming more popular since two double ‘AA’ batteries can produce between 3.0V and 3.3V.
